SQLSetConnectInfo Function

  • Artikkeli

Conformance
Version Introduced: ODBC 3.81 Standards Compliance: ODBC

Summary
SQLSetConnectInfo is used to set the data source, user ID, and password into the connection info token for an application's SQLConnect call.

Syntax

  
SQLRETURN  SQLSetConnectInfo(  
                SQLHDBC_INFO_TOKEN   TokenHandle,  
                WCHAR *              ServerName,  
                SQLSMALLINT          NameLength1,  
                WCHAR *              UserName,  
                SQLSMALLINT          NameLength2,  
                WCHAR *              Authentication,  
                SQLSMALLINT          NameLength3 );

Arguments

TokenHandle
[Input] Token handle.

ServerName
[Input] Data source name. The data might be located on the same computer as the program, or on another computer somewhere on a network. For information about how an application chooses a data source, see Choosing a Data Source or Driver.

NameLength1
[Input] Length of *ServerName in characters.

UserName
[Input] User identifier.

NameLength2
[Input] Length of *UserName in characters.

Authentication
[Input] Authentication string (typically the password).

NameLength3
[Input] Length of *Authentication in characters.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

Diagnostics

Same as SQLConnect for input validation errors, except that the Driver Manager will use a HandleType of SQL_HANDLE_DBC_INFO_TOKEN and a Handle of hDbcInfoToken.

Remarks

Whenever a driver returns SQL_ERROR or SQL_INVALID_HANDLE, the Driver Manager returns the error to the application (in SQLConnect or SQLDriverConnect).

Whenever a driver returns SQL_SUCCESS_WITH_INFO, the Driver Manager will obtain the diagnostic information from hDbcInfoToken, and return SQL_SUCCESS_WITH_INFO to the application in SQLConnect and SQLDriverConnect.

Applications should not call this function directly. An ODBC driver that supports driver-aware connection pooling must implement this function.

Include sqlspi.h for ODBC driver development.
